What is the IUPAC name of this molecule with a dihalide alkyl chain?
When listing preferred IUPAC names, the ring prioritized over the chain (making it a substituent), especially when the chain is shorter than the ring.
First we label the carbon at the end of the chain as '1' and continue across the chain. The bromines are at positions 2 & 3, and it is a 5 carbon chain. So, we label it as pentyl chain and it therefore follows the IUPAC name is
